Paper Abstract

We propose and demonstrate a technique for cascading a microsphere and an abrupt taper together in a standard singlemode fiber. The proposed microsphere-taper cascading structured microfiber (MTCSM) was fabricated by fusion splicing and electric-arc discharge. Exposing the MTCSM segment to increasing temperatures results in a significant shift of the transmission notches towards longer wavelengths with a slope of approximately 17.24 pm/°C∇ from 35°C to 170°C, and the linearity is 99.8%. Due to its compact size and all-fiber configuration, the proposed sensor has advantages of good mechanical strength, simplicity and low-cost fabrication, such new device would find potential applications in communication and sensing fields.
